Answer:
A) Temperature
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response.
In this question given, the data is portraying the Temperature versus Photosynthetic rate. This means that the experimenter is testing to see the effect of varying temperatures on the photosynthetic rate. Hence, the TEMPERATURE is the independent variable because it is the variable being changed.
How do organisms affect one another's survival and environment ?
Why did people in England feel that it was reasonable that America paid more taxes?
Answer:
See below
Explanation:
The people in England felt that it was acceptable to make to colonists pay taxes because they felt that they still owned the colonists and could push them around as they wished. They also needed the money to pay for war debt. It was also a reaction to the protests that the Americans were performing.

A predatory fish evolves adaptations that make it more adept at catching smaller fish. In turn, the smaller fish evolve means to be evasive, leading to more selection on the predators to be still better able to catch their prey. The interaction between the two species is an example of a(n)
Answer:
an evolutionary race (i.e., coevolution)
Explanation:
Coevolution is a phenomenon where two or more species affect each other's evolution through the mechanism of natural selection. During coevolution, species start an evolutionary race, where one species adapt and change (i.e., evolve) in response to another species, thereby countering the adaptive effects of the first one. An example of coevolution is the evolutionary race between predators and preys, like the example above.
The interaction between the two species is an example of a(n) coevolution. To understand more about it......
Arms raceIn the coevolutionary arms race, there is selection pressure on both prey and predator. The predator evolves to catch the prey, and mutually the prey evolves to escape the predator. These arms race can be seen in Cenozoic mammals, where the size of the brains of predators and prey increased relatively over time. As the brain size of predators grew to become smarter to catch prey, the brain size of prey also grew to become smarter and able to escape predators. This process is called climbing coevolution, where predator adaptations are neutralized by prey adaptations, with no advance occurring. As a result, current predators are no better at capturing their prey than ancestral predators. Different from what happens in the evolutionary process, where evolution generates organisms that are better adapted than others
With this information, we can say that the coevolution of predator and prey is common in nature, and determines the survival of these species involved.

Answer: From the onlookers, the two are clearly far away. The two girls are Kelveys and the talker: "Many kids including Burnells do not even talk to them, they passed through Kelveys in the air ... Kelveys everyone ran away" (Mansfield 203) Negative feelings affect not only my own emotions, but for very young people there is the possibility that it will affect not only the other people but also how to handle themselves.

In addition to Kezia, the Burnell family thinks that himself is higher than others, especially in Kelveys. Burnells seems to define himself through his social position (or class), and Mrs. Kelvey is a working-class woman and Mr. Kelvey can happen in prison, Burnells himself as Kelveys I believe it is higher. There is also a sense that Burnel refuses Kelvey as they may be different from them.

Gram , coccus, chains, catalase -, gamma hemolysis, glucose fermentation, grows slightly on MSA (salt tolerant) other test: mannitol fermentation test results: >80% which other test(s) are recommended to further increase the accuracy of your identification This organism is .
Answer:
The name of the test which can increase the accuracy of the identification of the organism is Coagulase testing.
Explanation:
Given the points stated in the question, the organism most likely under scrutiny here is Staphylococcus Aureus. Science has shown that it is the most harmful of all of the many different staphylococcal bacteria that there is.
The best test for differentiating and identifying Staphylococcus Aureus apart from other types of other Gram-positive cocci is the coagulase test.
The coagulase test checks to see if the microbe can produce an exoenzyme called coagulase.
Coagulase - an exoenzyme, is usually produced by bacteria. This enzyme triggers the coagulation of blood or plasma.
Only the pathogenic or disease-causing forms of staphylococcus can produce this enzyme. The enzyme is qualified by the suffice "exo" because the enzyme is secreted externally and not internally. Also, its functions are external, not internal.
The Coagulase testing is of two types:
The Slide TestThe Tube TestIt is usually safer to use the test tube method. If one must rely on the slide test, the results must be read quickly as it is prone to false positives.

7. Chemical or physical factor that determines the number
of organisms in a population
Answer:INTERSPECIFIC COMPETITION
Explanation:
The physical factor that determines the number of organisms in a population is ; Interspecific competition
Interspecific competition in a population is a competition that exists between organisms of different species, while the competition that occurs within organisms of the same specie is termed intraspecific competition.
During Interspecific competition the different species compete for food, water and Habitat which every organism needs to survive, and in most cases the stronger specie overruns the weaker species and this will lead to the depletion in the number of the organisms of the weaker specie and an increase in the number of the stronger specie within the population.
Hence we can conclude that The physical factor that determines the number of organisms in a population is ; Interspecific competition .

The slow depolarization of the pacemaker cells is caused by the opening of the:_______.
Answer:
The slow depolarization of the pacemaker cells is caused by the opening of the non selective cation channels.
Explanation:
Pacemaker cells are specialized cardiac muscle cells with the task to create the rhythmic pulses that make the cardiac muscle contract properly, functioning as a whole and not as independent contractile cells.
One of the things that differentiate pacemaker cells from regular cardiomyocytes is that pacemaker cells slowly depolarize by themselves. This happens because when these cells are in phase 4, in a state of hyperpolarization, the 'funny current' appears to begin depolarizing the cell again.
Hyperpolarization usually occurs because there's an outflux of potassium ions (which makes the inside of the cell much more negative than the outside of the cell) but, in pacemaker cells, the membrane becomes less and less permeable to potassium, which ends up decreasing the outflux of this ion. Along with this change in potassium's electrical conductance, the funny current increases the permeability of sodium, which means that there's also a sodium influx happening at the same time, helping in the depolarization process.
This mixed sodium and potassium permeability is one of the key features of the funny current, and is possible thanks to the opening of non-selective cation channels in the membrane that allow the passing of any cation following their specific chemical gradients.

Which of the three traits considered in this film (bipedality, extensive tool use, and large brains) were present in the 3.2-million-year-old Australopithecus fossil (Lucy)?.
Answer:
The bipedality
Explanation:
One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size because Lucy actually had a small skull which could indirectly be translated to small brain size.
NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.

Answer:
Hydrophobic areas move away from water.
Hydrophilic areas are attracted to water.
Hydrophilic regions of the protein are attracted to other hydrophilic regions.
Explanation:
Proteins are made up of amino acids. The side chains of these amino acids determine whether they are polar or non-polar. Hydrophilic amino acids are the types that are soluble in water and their side chains are polar. They are attracted to protein parts that are water-soluble. Examples are Glutamate and Lysine.
The hydrophobic amino acids have non-polar side chains. They withdraw from water by taking on an oily form. They are attracted to parts of the protein that are not aqueous. Examples are Valine and Tyrosine.
Answer:
1. Hydrophobic areas move away from water.
2. Hydrophilic areas are attracted to water.
5. Hydrophobic and hydrophilic interactions cause protein folding.

Answer:
Bare soil is exposed, weeds and grasses colonize, perennial plants are established, shrubs appear, trees appear, and forest results
Explanation:
This question describes a secondary succession, which is a colonization that occurs after a natural disaster has caused damage to an ecosystem. In secondary succession, SOIL, is already present, hence, there is rapid initial recolonization by GRASSES AND WEEDS.
The colonization of grasses and weeds is soon followed by the establishment of PERENNIAL PLANTS, after which SHRUBS appear, then TREES until a stable or climax ecosystem of FOREST results.
